dark glass, the whole app: frost on every pane, and the periscope pattern for every glass bar the frost sits under - backdrop-filter black-flattens over see-through ground (measured 3-vs-40), so bars over frost blur a scroll-synced clone behind a static band cut instead; the bar moved out of the scroller (pane shell, inner .content keeping the closest-contract, the old negative-margin flow replayed by a spacer after the artist page's sticky physics named the scrollport padding sacred); painted pages declare data-painted and keep the real backdrop bar, which is how the artist hero runs under the glass again; np wash rides the scroll away and dissolves to frost like the album banner; perf measured to vsync - 142px blur wraps (27.9ms frames down to 6.9), idle scroll-gated reclones, clip-path band, content-visibility on library rows, async cover decode; mini frosts over the mini:glass channel and the rest-frame flags ride window config because the env-var lane dies on some webview2 runtimes
